Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

5 highlights from the 2018 Petersen Automotive Museum Auction

From the avant garde exterior design to the collection of vehicles between the walls, the Petersen Automotive Museum in Los Angeles is one of the coolest car museums in the U.S., and possibly the world. Among several others, the Petersen has two featured exhibits, The Porsche Effect and Legends of L.A. But the museum has a different type of viewing coming up at which you could touch, or even buy, a variety of special vehicles. After hosting its SoCal auction on the coast in Santa Monica for several years, RM Sotheby's has moved the event to the more central location of the museum. In addition to several works of art, the auction which takes place the weekend of December 7, will show several dozens of blue-chip vehicles, chosen by RM Sotheby's 30 car specialists. After sorting through lots that range from microcars to new-age supercars, here are five of the highlights that caught our eyes. 1956 Ferrari 290 MM by Scaglietti Projected Value: $22,000,000-$26,000,000 Without question, this is the crown jewel of the entire show. As the eldest and most experienced of the 11 total Ferrari lots, its estimated value of $26 million is more than five times the values of the other five cars listed below combined. From the jump, Ferrari threw the 290 into the line of fire. Starting its life with a four-cylinder 860 Monza engine and a Tipo 520 chassis, its first race was the Mille Miglia. Peter Collins was behind the wheel and racing photographer Louis Klemantaski was his copilot. Ferrari took the top five spots in the race, with this car, chassis No. 0628, finishing second. It went on to see multiple races and took on multiple forms, including a V12 swap at one point. After switching through the hands of multiple owners, it was sent to Ferrari Classiche in Maranello, where it was restored to its form at the time of the 1957 12 Hours of Sebring. It retains its original chassis, original bodywork, and original transmission, and houses the V12 from its 290 MM spec. The restoration was completed in 2015, and the car remains in incredible shape today. 1971 Lamborghini Miura P400 SV by Bertone Projected Value: $2,100,000-$2,500,000 Simply put, the Miura is one of the most significant supercars, and therefore one of the most important cars, of all time. Its two-seat, mid-engined configuration seismically shifted what a performance could and should look like, and its V12 gave it the power to be the fastest car in the world when it debuted.

Are you the next Porsche 911 GT3 RS or GT2?

Porsche typically keeps to a suitably fast schedule when it comes to rolling out increasingly hard-core performance versions of the 911. After the 997 Carrera debuted in 2004, the GT3 version followed in 2006, and by the end of the 2007, Porsche had rolled out both the GT3 RS and GT2 versions. Then the facelifted 997.5 came out in 2008 and it was back to the start: the GT3 came in 2009, the GT3 RS and GT2 RS in 2010, and the GT3 RS 4.0 in 2011. But things have slowed down some with the latest 991 generation.
The new Carrera came in 2011 and the GT3 followed in 2012. By recent history's example, we should have at least two more hardcore models by now, but we don't. Maybe the engineers in Zuffenhausen have had their hands full fixing the spontaneous-combustion issues with the existing GT3, or maybe their attentions have been focused elsewhere altogether. But if these spy shots are anything to go by, it seems like they're back on the job.
Now we don't know if this prototype foreshadows a new GT3 RS or a GT2, but it sure looks more hard-core than the existing GT3 that many purists have derided as too soft, what with its automatic transmission and four-wheel steering.
